Schmersal BN 20-01Z magnetic switch 101172087

The BN 20-01Z-M16 from Schmersal is a rectangular magnetic sensor with a durable aluminum housing, designed for use in industrial applications. The sensor operates based on a magnetic principle and is particularly suitable for safety-critical environments requiring high mechanical durability and reliability.

With a mechanical lifespan of at least 1 billion switching cycles, the BN 20-01Z-M16 is highly durable. The sensor features a side actuation plane and an active area on the side. Actuation is performed by specific magnets that must be ordered separately.

The sensor has an IP67 protection rating and can operate in ambient temperatures ranging from -25 °C to +90 °C. With a switching voltage of up to 250 VAC and a maximum switching current of 3 A, the sensor provides reliable switching performance.

Important Note: The actuator is not included in the delivery. Recommended actuators are models BP 10, BP 20, BP 31, and others.
